Former rugby player Alex Olaba Mahaga was on Thursday night arrested over claims of attempting to murder a witness in a rape case he is facing.
Olaba and fellow former player Frank Wanyama are facing gang rape charges before a Milimani court and are both out on a Sh300,000 cash bail.
Police said Olaba was planning to kill a key witness in the case in efforts to defeat justice.
He was arrested in Nairobi West where he was meeting an undercover detective planning the said murder of the witness in the case.
Police said they recovered two mobile phones from Olaba which are undergoing forensic analysis to establish if there were more players in the crime.
Olaba had apparently approached another party seeking ways of eliminating the witness in the case before police were informed.
The officers then sent undercover officers who posed as possible executors of his mission before they pounced on him.
After his arrest, Olaba told police he had been possessed by satanic spirits.
He was on Friday expected in court to face charges of attempted murder and conspiracy to defeat justice.
